   Abstract : In this report we will calculate the amplitude for a scalar-to-scalars (φ3  φ2φ2) decay which involves a triangle loop. We compute the real and imaginary part of the amplitude separately and will argue that this is much more straightforward and practical in this case rather than having to deal with or worry about branch cuts of logarithms.
